    Thanks to everyone that has liked the image, I'm glad you enjoyed the view. Demon and Alan, thanks for the affirmation of the field with a 5". It really does give a good perspective.

    M77 and Friends

    Not really a 5 inch refractor target however; I was looking for something different to image. Now there is a super nova in M77. http://www.pbase.com/grahammeyer/image/168495360/original Details if they don not show up.

  3. Hi, it is not in all of my images and only seems worse when the scope is pointed up nearer vertical. I'll have to pull the imaging train apart and have a look, it appears to be an internal reflection to me.
  4. Hi, has anyone got any ideas what the artifact in my images is. This time it has appeared in the top right corner pointing of the witches head nebula, if I point in the other direction it is in the top left, so is in the same spot, I think. The thing is, it is not in all of my images and seems to only occur on long exposure when the scope is pointing high. Apart from dismantling my imaging train, I have checked for stray light, looked down the tube, etc. PS: I think PixInsight might flip the image, might be in the other orientation??
  5. Most people build stuff that is well over engineered with good intentions and we are usually using gear that is not significant in weight. When I rebuilt my obs at my brothers place and incorporated his setup, we built piers with 203mm inside diameters and 9mm thick walls, i.e. very strong. They are bordering on too big with telescope and pier strike a reasonable concern for me as I'm using an FLT132 and quite a long imaging chain. I just need to be careful where I place what and when. This doesn't mean that we need to go skinny and flimsy, we need to really think about what we are doing. If I was to redo the piers, I would use 150mm pipe with 4 ribs at 90 degrees to each other around the pipe, that would be significant enough for an EQ5/6 or or Losmandy G8/11. And I would probably use square tube rather than round. http://www.pbase.com/grahammeyer/image/165086953 YMMV.

    Messier33 The Triangulum Galaxy in HaLRGB

    Very nice, looks beautifully processed. I think the CMOS cameras images have a bit of a different feel to them compared to CCD.

    NGC 104 and 121

    Thanks to all for taking a look and for the likes, I'm glad you enjoyed the view. I hope you enjoy my reprocess as much as the original. I think it looks a lot better and hopefully a bit more natural. http://www.pbase.com/grahammeyer/image/168299434 Cheers and clears!

    47 Tuc & NGC121

    Thank you for taking a look. The beauty is that it is a naked eye object so you only need very short time to get good data.
  9. Both of these globulars are in the constellation Tucana but are in two different galaxy. 47 Tuc is in our own Milky Way and NGC121 is in the Small Magellenic Cloud. NGC121 may even be larger than 47 Tuc. http://www.pbase.com/grahammeyer/image/168197638/original Telescope: William Optics FLT132 Guide Scope: QHY OAG Camera: QHY9 Mono @ -20c Filter Wheel: QHY 7 position Ultra Slim Filters: QHY 36mm unmounted L R G B HA OIII SII Guide Camera: QHY5L-II Mount: AZ-EQ6 Mount Control: EQASCOM Focusing: SharpSky Pro and Sequence Generator Pro 3 (automated) Bahtinov Mask: No Capture Software: Sequence Generator Pro 3 Guiding Software: PHD2 Calibration and Stacking Software: PixInsight Processing Software: PixInsight Number and Type of Data Frames: L= 19X300 sec, L =7X120 sec, L= 14x30 sec, R= 10x180 sec, G= 10x180 sec, B= 10x180 sec Ha= x , SII= x , OIII= x .

    NGC 104 and 121

    I had the chance to finish my image of NGC104 and the field of view also allows NGC121 to sneak into the frame. NGC121 is located in the Small Magellanic Cloud, so two globulars in two galaxies. I had to murder the data a bit as for some reason my flat frames have started over correcting so I processed it to hide the dust bunnies. Happy enough with the result. You can use the size buttons on the bottom of the page if you wish a different size. http://www.pbase.com...197638/original For interest and comparison, here are some specs for both objects, courtesy of Wkipedia (accuracy not verified) NGC121 NGC104 Constellation Tucana Tucana Distance 199 Kly 13,000 +/- 1,100 ly Magnitude 11.24 4.09 Size 175ly 60ly Age 10 billion years Not given There are differing estimates for both of these, NGC 121 seems to have more consistent data, NGC104 seems to vary a bit in distances and a lot in size, from 60 to 150 ly. Thanks for looking.
  11. Hi. In reference to this rule, does this exclude submitting a colour version if I have already submitted a black and white image of the same object? Thanks.

    M17 Take 2

    I felt that my other version was not the best and after getting my Photometric Colour Calibration working I have decided to do a reprocess. http://www.pbase.com/grahammeyer/image/167991880/original.jpg Image details Telescope: William Optics FLT132 Guide Scope: QHY OAG Camera: QHY9 Mono @ -20c Filter Wheel: QHY 7 position Ultra Slim Filters: QHY 36mm unmounted L R G B Guide Camera: QHY5L-II Mount: AZ-EQ6 Mount Control: EQASCOM Focusing: SharpSky Pro and Sequence Generator Pro 3 (automated) Bahtinov Mask: Yes (initial focus) Capture Software: Sequence Generator Pro 3 Guiding Software: PHD2 Calibration and Stacking Software: PixInsight Processing Software: PixInsight Number and Type of Data Frames: L=30X10 min, R=6x7 min, G=6x7 min, B=6x7 min Ha= x , SII= x , OIII= x .

    M17

    Hello! Wow, there are really some more great images here, keep up the good work everyone. This one has been another struggle for me, I am not getting the best out of my scope and kit, with silly little issues all the time. Might be time to re-assess my options. Anyway, it has taken 12 months of data collection to get this far on this one and where I am in Australia the weather has been rubbish for winter and data collection has been hit and miss. So here it is, M17 in LRGB. http://www.pbase.com/grahammeyer/image/167991880/original.jpg Apart from stretching, colour calibration, enhancing and a couple of other steps, there is no image sharpening, it is straight from the scope. If anyone has any thoughts re sharpening, let me know. Thanks for looking.
